Benefits of technology

This solution effectively reduces uncontrolled hot air escapes, prevents condensation issues, and enhances energy efficiency by utilizing latent heat for direct substrate heating, improving the drying and fixing processes in printers and copiers.

Problems solved by technology

When hot, moist air escapes e.g. from a fuser, this can lead to undesirable heating of other machine parts and / or condensation on cold surfaces such as paper guiding plates, output rollers, etc., which potentially causes printing defects.

Embodiment Construction

[0067]FIG. 1 shows a schematic view of an image forming apparatus or printing system comprising a recording substrate treatment apparatus 10 according to the invention. FIG. 2 schematically shows further details of the recording substrate treatment apparatus 10.

[0068]The treatment apparatus 10 comprises a drying / fixing device 12 for drying a recording substrate 14 and thereby fixing a printing substance on the recording substrate 14.

[0069]The printing system further comprises an image forming unit or printing unit 16 that comprises at least one print head 18. In FIG. 1, five ink jet print heads 18 are arranged above a sheet transport path 19 that is schematically illustrated by a dashed line. Sheet transport means 20 are arranged for transporting a recording substrate 14, e.g. a paper sheet, along the transport path 19 past the print heads 18 and further through the recording substrate treating apparatus 10. For example, the print heads 18 print a printing substance in the form of a...

Abstract

A recording substrate treatment apparatus, includes a heating device for directly heating a recording substrate, a condenser for condensing liquid from air from surroundings of a recording substrate, and an energy transfer system arranged for transferring energy from latent heat, which is released by the condensing of liquid by the condenser, to the heating device. Further, a method of drying a recording substrate and a method of fixing a printing substance on a recording substrate include heating a recording substrate by a heating device; condensing liquid from air from surroundings of the recording substrate; and transferring energy from latent heat, which is released by the condensing of liquid, to the heating device.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a Continuation of PCT International Application No. PCT / EP2011 / 066150 filed on Sep. 16, 2011, which claims priority under 35 U.S.C. §119(a) to Patent Application No. 10179943.5 filed in Europe on Sep. 27, 2010, all of which are hereby expressly incorporated by reference into the present application.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a recording substrate treatment apparatus, in particular a recording substrate treatment apparatus for a printer or copier. For example, the recording substrate treatment apparatus comprises at least one of a drying device for drying a recording substrate and a fixing device for fixing a printing substance on a recording substrate. For example, the fixing device may be or comprise a fuser.[0004]2. Description of Background Art[0005]In the field of copying and printing, it is known to dry or fix prints on a recording substrate. For exampl...
